Introduction to PDR

The clinician portal provides a central location for eye care specialists to find information on proliferative diabetic retinopathy (PDR), including pathophysiology, diagnosis, and management.

Around 29% of American adults with diabetes have diabetic retinopathy (DR).1 This is a growing problem as the number of people living with diabetes has increased over time with only around 60% of them receiving the appropriate screening.1,2 This, combined with the lack of symptoms in the earlier stages, makes it unsurprising that DR is the leading cause of new cases of blindness in adults.1 According to a CDC study, around 15% of the over 4 million Americans with diabetic retinopathy had vision-threatening complications.2

Even with intervention, retinal damage arising from PDR may be irreversible and can be associated with permanent vision loss.3 Preventing progression of diabetic eye disease to vision-threatening forms of DR such as PDR and DME should be the primary goal in diabetic vision health.3 Working to improve DR awareness as well as access to essential screening and treatment may help to reduce the burden of diabetes-related vision loss.2
